[Solved] Dosen't work with MVVM pattern?

[samin]

Hi , I used mvvm pattern to prepere data for scheduler ... below you can see my sumrized code. when project start data loaded just today appointment load, when you change visible range ,data loaded truly and "Timeslices" property in "Schedule" updated , but doesn't show nothing.

public class Scheduler : INotifyPropertyChanged
   {

      ....
       private Schedule _timeSliceSchedule;
       public Schedule TimeSliceSchedule
       {
           get
           {
               return _timeSliceSchedule;
           }
           set
           {
               _timeSliceSchedule = value;
               OnPropertyChanged("TimeSliceScheduler");
           }
       }

       private bool _isGettingData;
       public bool IsGettingData
       {
           get
           {
               return _isGettingData;
           }
           set
           {
               _isGettingData = value;
               OnPropertyChanged("IsGettingData");
           }
       }

       private string _busyDescription;

       TimeSliceTypeCollection _timeSliceTypes = new TimeSliceTypeCollection();
       public TimeSliceTypeCollection TimeSliceTypes
       {
           get
           {
               return _timeSliceTypes;
           }
           set
           {
               _timeSliceTypes = value;
               OnPropertyChanged("TimeSliceTypes");
           }
       }

      ....

       #region INotifyPropertyChanged Members

       protected virtual void OnPropertyChanged(string propertyName)
       {
           if (PropertyChanged != null)
               PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
       }
       public event PropertyChangedEventHandler PropertyChanged;
       #endregion
   }

public class Schedule : ViewModelBase, INotifyPropertyChanged
    {


        ....

        private TimeSliceCollection timeSlices;
        public TimeSliceCollection TimeSlices
        {
            get
            {
                return this.timeSlices;
            }
            set
            {
                this.timeSlices = value;
                this.OnPropertyChanged("TimeSlices");
            }
        }

       ...


        #region # Events and Handler

        public delegate void VisibleRangeChangedHandler(DateTimeSpan datetimeSpan);
        public event VisibleRangeChangedHandler VisibleRangeChangedEvent;

        #endregion

        #region INotifyPropertyChanged Members

        protected virtual void OnPropertyChanged(string propertyName)
        {
            if (PropertyChanged != null)
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
        public event PropertyChangedEventHandler PropertyChanged;
        #endregion
    }

Hello samin,

RadScheduleView is designed to work in MVVM scenarios, you can check our help article regarding this here.
If you still experience the issue, please send us a simple runnable project where it can be easily reproduced. Thanks in advance
